  • Product Details

 Anodizing  define:
 Anodizing  is an electrolytic passivation process used to increase the thickness  of the natural oxide layer on the surface of metal parts. The  process is called anodizing because the part to be treated forms  the anode electrode of an electrical circuit.Anodizing increases  resistance to corrosion and wear, and provides better adhesion  for metal.


Anodizing  advantage:
 Anodizing  films can also be used for a number of cosmetic effects, either with thick  porous coatings that can absorb dyes or with thin transparent coatings that add interference effects to reflected light.Anodizing  is also used to prevent galling of threaded components and to make  dielectric films for electrolytic capacitors. Anodizing films are  most commonly applied to protect aluminium alloys.Anodizing  changes the microscopic texture of the surface and the crystal  structure of  the metal near the surface. Thick coatings are normally porous, so a sealing  process is often needed to achieve corrosion resistance. Anodized aluminium  surfaces, for example, are harder than aluminium but have low to moderate wear  resistance that can be improved with increasing thickness or by applying  suitable sealing substances. Anodizing films are generally much stronger and  more adherent than most types of paint and metal plating, but also more  brittle. This makes them less likely to crack and peel from aging and wear, but  more susceptible to cracking from thermal stress.

 

Anodizing  aluminum Application:
 Protects  satellites from the harsh environment of space.
 Used  in one of the world's tallest buildings --- the Sears Tower in Chicago,  Illinois.
 Provides  attractive, minimum-maintenance, highly durable exteriors, roofs, curtain  walls, ceilings, floors, escalators, lobbies and staircases in skyscrapers and  commercial buildings throughout the world.
 Revolutionized  the construction of computer hardware, exhibit displays for trade shows,  scientific instruments, and a constantly expanding array of home appliances, consumer  products, and building materials.
 Considered  environmentally safe, producing few, if any, harmful effects on land, air, or  water.
